Mark Judson and Dr. Val Jo Anderson, Plant and Animal Science The Uncompahgre Plateau Project involves a series of studies to help with the production of native seeds for large-scale restoration of this Colorado Plateau Region. Studies are being conducted at various research centers throughout the United States. The present study at Brigham Young University […]
title
Scott A. Davis and Dr. Bruce Roundy, Plant and Animal Sciences The invasion of non-native species, mainly cheatgrass (Bromus tectorum), into our rangelands, especially following the destruction caused by wildfires, has made it necessary to find viable options for the restoration of native plant species to these areas. The aim of this project was to […]
Analytical and Toxicological Assessment of Carp collected from Utah Lake
Holly Clayton and Dr. Richard Kellems, Plant and Animal Science The June sucker was once the most abundant fish species in Utah Lake and its tributaries. Since April 30, 1986, the June sucker has been on the endangered species list. Some declines in species abundance is due to the competition of nonnative species and degraded […]
Endophyte Effects on Drought Resistance in Forage Grass
Alan Chambers and Dr. Brad Geary, Plant and Animal Sciences Introduction Endophyte infected, drought resistant crops are gaining in popularity with growers because irrigation can be expensive and rainfall unpredictably sparse. For this reason there has been a recent explosion of research relating to the benefits of plant microbe interactions. Our investigations were focused on […]
PRESSURIZED, CONTROLLED ATMOSPHERES AS A METHOD OF LONGTERM PRESERVATION OF FRUIT
Stuart C. Wooley and Dr. Darrell J. Weber, Botany and Range Science The bane of all fruit growers and sellers is that fruit rots either before and during transport or on the store shelf. This creates income loss for the grower and grocer and reduces quality of produce. For example, some fruits like strawberries have […]
Foraging habits of Bighorn Sheep (Ovis Canadensis)
Joshua Whitaker and Dr. Todd F. Robinson, Plant and Wildlife Sciences Introduction Over the course of the last few months the final foraging samples have been collected on five populations of bighorn sheep (Ovis canadensis) in the Great Basin and along the Wasatch Front. These locations include the Newfoundland Mountains, Antelope Island, American Fork Canyon, […]
Virulence Variation in the Grass Seed Pathogen Pyrenophora semeniperda
Thomas Stewart and Dr. Phil Allen, Plant and Wildlife Science Bromus tectorum, an invasive annual grass weed, is one of the main plants responsible for an increase in fire frequency and intensity in western wildlands. Wildfires cost the U.S. Forest Service over a billion dollars a year to fight. These fires destroy native vegetation communities […]
Characterization of a cDNA Encoding β-amyrin Synthase Involved in Saponin Biosyntheses in Chenopodium Quinoa
Derrick J. Reynolds and Dr. P. Jeff Maughan, Plant and Animal Sciences Quinoa (Chenopodium quinoa) is an important crop for subsistence farmers in the Altiplano (high plains) of Peru, Bolivia, and Argentina. Quinoa’s seed is highly nutritious, but the seed coat of quinoa contains several anti-nutritive triterpenoid saponin compounds. The biological role of saponins in […]
Identification of Tomato Spotted Wilt Virus Resistance Genes in Solanum lycopersicum (Tomato) using AFLP
David L. Price and Dr. Mikel R. Stevens, Plant and Wildlife Sciences The tomato is susceptible to more than 200 diseases. Tomato spotted wilt virus is one of the most damaging pathogens in tomatoes. Due to its wide spread, TSWV has become an important limiting factor in tomato production worldwide. Most often the virus is […]
Genetic Variation Within and Among Populations of Draba asterophora (Brassicaceae) in Lake Tahoe Nevada
Danny Nielsen and Dr. Loreen Allphin, Department of Plant and Wildlife Sciences The rare endemic Lake Tahoe Draba (Draba asterophora) plant is under threat of extinction due to completed and proposed grating of ski runs on two ski resorts near Lake Tahoe where this species is located. This is of concern to both the US […]
